Abstract:
Previous research has demonstrated the displacement of leisure items by edible items in the context of preference assessments. Recent research has further evaluated this phenomenon by manipulating the magnitude of access to leisure items and evaluating the effect on preference when given the option between leisure and edible items (e.g., Clark et al., 2020). The current study replicated and extended Clark et al. (2020) by including a reversal design to evaluate the effects of differential magnitudes on participants' selection of a leisure item relative to an edible item. Increases in the duration of access to the leisure item resulted in participants choosing the leisure item over the edible item. Implications for practice and future research are discussed.

Simple Pendulum
The period of a simple pendulum depends on two factors: its length and the acceleration due to gravity. The period is completely independent of any other factors, such as mass or maximum displacement. For small displacements, a pendulum...
